Over the last few decades, agrochemicals have been partially associated with a global reduction in bees' population. Toxicological assessment is therefore crucial for understanding the overall agrochemical risks to stingless bees. Therefore, the lethal and sublethal effects of agrochemicals commonly used in crops (copper sulfate, glyphosate, and spinosad) on the behavior and gut microbiota of the stingless bee, Partamona helleri, were assessed using chronic exposure during the larval stage.

This is a case series study with five volunteers who received a single application of capacitive RF (BTL-6000 TR-Therapy Pro®) in the right infraumbilical abdominal region, with epidermal temperature above 40°C, for 10 min (2 min per applicator area), and the skin of the contralateral region was used as control. After 30 days, on average, the skin of the abdominal region was collected for histological analysis and stained with hematoxylin and eosin, Picro-sirus, and Verhoff.

To evaluate the effect of RF on patellar ligament repair of Wistar rats, cross-sectional incision (60% of the width - grade I) was performed in patellar ligaments of the groups: lesion (L, n = 7), treated with RF on the 5-day (5RF, n = 7) and 7-day (7RF, n = 7) post injury were compared to control group (C, n = 7). Histological evaluation, immunohistochemistry, morphometry and statistical analysis were performed.

Objectives: To evaluate the effects of carboxytherapy upon human skin collagen and elastic fiber synthesis.
Methods: Case study of nine volunteers who received a single application of carboxytherapy in the left infraumbilical region, with infusion rate of 100 mL/min and 0.
Background: Equipment that acts in the reduction in adipose tissue are becoming widely investigated. One of the resources that begin to gain recognition is radiofrequency.
Purpose: To verify the existence of scientific evidence and the methodological quality of the articles on the effects of radiofrequency in the reduction in adipose tissue.
There is scarce evidence on suitable approaches for the treatment of unresponsive or residual periodontal sites in diabetic patients. This study assessed the effects of surgical debridement (SD) and nonsurgical debridement (NSD), associated with amoxicillin and metronidazole, on clinical and immunological outcomes of residual pockets and adjacent healthy sites in patients with type 2 diabetes. A split-mouth, randomized controlled trial was conducted in 21 patients presenting at least 2 residual pockets in contralateral quadrants 12 months after basic nonsurgical periodontal therapy.

Radiofrequency (RF) is a method that uses electric current for heating layers of the skin. Both techniques are indicated for the treatment of skin laxity.

Objective: The aim of this study was to evaluate the effects of application of microdermabrasion in human skin rejuvenation.
Methods: Eleven women who were undergoing abdominoplasty were considered.
Aim: This study evaluated the effects of surgical (SD) and non-surgical (NSD) debridements, associated with systemic antimicrobials, on clinical and immunological outcomes of residual pockets [RP; probing depth (PD) ≥5 mm with bleeding on probing] in type 2 diabetics.
Material And Methods: A split-mouth, randomized controlled trial was conducted in 21 subjects presenting at least two RP per contralateral quadrant. Subjects received metronidazole plus amoxicillin for 10 days and, contralateral quadrants were assigned to receive SD or NSD.

Background: This study compares the levels of cytokines and bone-related factors in the gingival crevicular fluid (GCF) of systemically healthy patients with chronic periodontitis (CP); and better-controlled, and poorly controlled patients with type 2 diabetes and CP.
Methods: Thirty-seven patients with type 2 diabetes and CP and 20 systemically healthy patients with CP were enrolled in this study. The patients with diabetes mellitus were categorized as better-controlled (n = 17; HbA(1c) levels ≤8%) or poorly controlled (n = 20; glycated hemoglobin values >8%).
Aggressive periodontitis is characterized by a rapid and severe periodontal destruction in young systemically healthy subjects. A greater prevalence is reported in Africans and African descendent groups than in Caucasians and Hispanics. We first fine mapped the interval 1q24.
View Article and Find Full Text PDFBackground: This study evaluated the clinical and metabolic effects of full-mouth scaling and root planing (FMSRP) compared to partial-mouth scaling and root planing (PMSRP) in patients with type 2 diabetes and chronic periodontitis, and it assessed the impact of the glycemic status on the clinical and metabolic response to periodontal therapy.
Methods: In this clinical trial, 18 subjects with diabetes received FMSRP in a maximum of 24 hours, and 18 subjects received PMSRP in a maximum of 21 days. Visible plaque accumulation, bleeding on probing, suppuration, probing depth, clinical attachment level (CAL), and glycosylated hemoglobin (HbA1c) levels were obtained at baseline and at 3 and 6 months post-therapy.
Background: The aim of the present case series was to evaluate the effects of a surgical anti-infective mechanical therapy for peri-implantitis on clinical parameters and tumor necrosis factor-alpha (TNF-alpha) levels at 12 months post-therapy.
Methods: Ten patients with peri-implantitis were treated with open surgical debridement, abrasive sodium carbonate air-powder, and resin curets. Clinical parameters were recorded before and 3 and 12 months after therapy.
Objective: This study assessed gene expression by quantitative polymerase chain reaction of inflammatory- [interleukin (IL)-12, tumor necrosis factor-alpha (TNF-alpha), IL-4, and IL-10] and osteoclastogenesis-related factors [receptor activator of NF-kappaB ligand (RANKL) and osteoprotegerin (OPG)] in sites exhibiting different severities of peri-implant disease.
Material And Methods: Peri-implant soft tissue biopsies (n=48) were harvested from healthy implant (HI), mucositis (MC), initial peri-implantitis (IP) and severe peri-implantitis (SP) sites.
Results: IL-12 and TNF-alpha mRNA levels were higher in SP, followed by IP and MC (P <0.
Background: The objectives of this study were to clinically and immunologically assess the effects of mechanical anti-infective therapies for mucositis and peri-implantitis and to compare the levels of cytokines in untreated and treated peri-implant diseased sites to healthy ones.
Methods: Titanium dental implants were assigned to one of the following groups: healthy (n = 10) = control; mucositis (n = 10) = mechanical debridement using abrasive sodium carbonate air-powder and resin curets; and peri-implantitis (n = 20) = open surgical debridement using abrasive sodium carbonate air-powder and resin curets. Visible plaque accumulation, marginal bleeding, bleeding on probing, suppuration, and probing depth were assessed at baseline for all groups and at 3 months after therapies for diseased groups.
The aim of this study was to evaluate the prevalence of peri-implant diseases around Branemark system implants in Brazilians and the possible relationship with periodontal bone loss, systemic condition, and demographic profile. A total of 113 individuals were enrolled in this study, and they received 347 implants. The implants were clinically and radiographically examined and diagnosed as healthy implants, mucositis, or peri-implantitis.

Materials And Methods: Thirty-six flattened bovine roots were randomly assigned to one of the following groups: group 1 (n = 12): Er:YAG laser (2940 nm), 120 mJ/pulse, 10 Hz, 8.4 J/cm2; group 2 (n = 12): ultrasonic system; and group 3 (n = 12): manual curette.
The influence of direct electric stimulation on nerve regeneration was studied in a model of crush injury of the sciatic nerve of rats. Forty-three rats were used and distributed in four groups according to the procedure: (1) intact nerve, inactive circuit; (2) crush injury, inactive circuit; (3) intact nerve, active circuit; (4) crush injury, active circuit. The low intensity continuous current circuit (1 microA) was implanted in the lumbar region, the anode being fixed to the muscles proximally and the cathode below the nerve distally to the lesion site.
